Only thee color texture loads from poser. You have to go back and load the transparency into the second box of the texture window. When I import from poser I usually start with a new blank scene. I import and ungroup the figure. Clicking on the figure selects one material, usually the skin or clothing. Click on the material editor and check out the properties and adjust as needed. Since it's really impossible to touch the iris of the eye in bryce I use the tab button on the keyboard. Each time you press this it steps to the next material in the figure. It also lets you select without the risk of moving that object with the mouse click. I walk through the whole character till it looks right, then I regroup it. I click on the character and go to the top menu bar and press copy. I open the original scene file without closing bryce. When the scene comes up,(in your case the boat, water , and rocks) I go back to the top menu and press paste. The figure should appear in the scene. Position it and save the file.
